The inventionrelat to racks or boxes in which a coil of strip steel orthe like may be carried. for unwindinggto pass contlnu.- ously througharolling mill, an anneallng apparatus, or for other endwise o erations onthe strip; and the object of the lmprovement is to connect a pluralityof coil carryso that either one of the boxes may be moved alternatelyinto and out ofalinement with the o rat-ind a aratus. v

A Edil ofbstrri; steel is very heavy and cumbersome to handle and tolproperly position by manualmeans, especially, when the coiled strip hasa length ofa hundred feet or more'gand a width of some twenty inches, asin recent practice; and before proceeding with a continuous endwiseoperation upon the strip, the coil must be properly positioned in exactaline'ment w1th the operating apparatus, and it is frequently necessaryto cut or trim' or otherwise work upon the forward end of the-stripbefore 1t can properly enter the apparatus.

Furthermore a series of strips are frequently woun one upon another,which makes a very heavy coil and whenv the 'suC- 'cessive strips arenunwound forrolling it is frequently necessary to cut the fish-tail fromthe next coil before it can be processed.

For the purpose of facilitating the han- .dling of such a coil, and forrapidly bringing it in proper position and exact condition for aVcontinuous operation upon the strip, the' present improvement consistsin joining tworor more individual boxes side by side to form a commoncarrier, and in mounting the same upon a track or bearlng foralternately shifting either one of theboxes into proper position forunwinding a coil therein, and another box in.A proper position forreceiving a `fresh coil and preparing it for a continuous operation.

' A preferred form of the invention and some modifications thereof areillustrated in the accompanying drawings, forming part hereof, in which-Figurel is a plan view of the improved box carrier in conjunction with atrain of rolls; Fig. '2, of the coil box carrier; A

a side elevation partly in- .section-Y fFig.' 3, a plan view of the samewith the .i i

pit cover removed;v

Flg. 4, a plan view of a modified arrangement of the box carrier; and

F 1g. 5, a side elevation of the same.

ySimilar numerals refer to similar parts throughout the drawings.

The carrier A or A may Ainclude'two or more co1l boxes 6 or 6 connectedtogether by a suitable web or frame plate 8 Aor 8; and the side walls 9or 9 of the boxes may open on the rear for receiving a trunnion bar orsplndle 11 or 11 located in the axis of the bundle.

'be' provided with. journal bearings 10 or 10 The carrier is preferablymounted in a pit'V B or B with the-normal bottom 1 2 or 12` in the'plane. of the factory floor; .and a coverplate 13 or 13 may be securedto the carrier as in Figs. 1 and 2 or to the floor as in Figs. 4 and 5to close the opening of the pit; and in either case the cover plateforms a platform upon which a coil can -be rolled for entering it intoone of the boxes.

The bottom of each box may be formed as a hopper vwith an openingtherein for freely receiving the coil when its-.trunnion bar ismountedin the bearings; and the side walls of the boxes are preferably in.elined upwardand rearward from the bearings, so as to form skids uponwhich the trunmons may bear and may be yguided into the bearings when aAcoil is rolled into the box from the factory'loor through the rear openend of the-box.

A's shown in Figures 1 andZ, the forward end of the carrier is providedwith flanged wheels 14 riding on an arcuate track l5 and the rear end ofthe carrier is provided with a radial'beam lrpivoted to a pintle. post17 at the center of the arcuate rail, 4so that the carrier may ride toand fro upon the rail by turning on the p intle post.

-r as shown in'Figures 4l and 5 the carrier may be provided at front andrear with parallel pairs of4 wheels 14 riding lon a track formed bystraight rails 15; upon which the carrier may ride fro.

A'cylinder 18 may be mounted for turning on-a pivotal post 19 with apiston rod laterallly to and i 2O pivotally connected to one side of thecarrier for moving the same to and fro by compressed a1r, steam or thelike in Well vknown manner.

boxes, While another coil 21 is being unstri Wound in a laterallyadjacent box for rolling through a mill C, as shown in Fig. l; and theyend 21 of the one coil can be cut or otherwise made ready While theother coil is being processed.

Furthermore, when a series of strips are wound on one coil, the carriercan be moved laterally when one strip is unwound for preparing the nextstrip; and at the same time another coil in another box is brought intoposition for unvvinding and rolling a therefrom. e claim:
